Find the time required for an object to fall to the ground from a building that is 1400ft high.
displacement, y=1400
acceleration, a=32 ft/s^2 (This is the acceleration due to gravity)
initial velocity, v=0 because it is dropped
There are a couple of equations you can use, here's one:

Ignore +\- because negative time has no meaning here.

t~~9.35414 s
If significant figures are important in your class, round off to 2 significant figures:
t~~9.4 s
Happy Calculating!!!
